Helena Day travels to Edinburgh, Scotland after her divorce, using her passion for photography to heal her wounds. But one night she catches something unusual on camera, and realizes in dread she's just witnessed murder. Hurrying over to help the victim, she is attacked. But her attacker is not a villain she can easily hate. It's a painfully beautiful vampire that sees something special in her.
Vampire nobleman Dorian McBain needs to activate Helena's hidden superpower in order to save his kind from the Prince of Midnight. For that, he needs to turn Helena into a vampire, reversing the aging process and granting her immortality, which he thinks is a fair trade. What he doesn't expect is the effect the new Helena will have on him. Will he lose control and take the woman for himself, or will he sacrifice his own desires and use her against the vampires' nemesis?
